MANHASSET, N.Y. Atheros Communications Inc. has announced what it claims are the first single-chip wireless local area network solutions that comply with PCI Express specifications.
The chips, designated the AR5006EX and AR5006EG, meet the IEEE 802.11 a/g and 802.11g specifications, respectively. They integrate a media access controller (MAC), baseband processor, and a high-performance 2.4/5-GHz radio or 2.4-GHz radio-in a low-cost digital CMOS design.
Atheros (Sunnyvale, Calif.) said these designs exploit the ability of the PCI Express bus architecture to support high-performance computing with up to 2.5-gigabit-per-second transmit and receive rates, which the company claims is a 150 percent improvement over the existing PCI architecture.
Both chips are said to provide seamless connectivity to Wi-Fi networks globally and support the industry's most robust security standard, IEEE 802.11i. A built-in AES encryption engine allows real-time encryption with no performance degradation in computing, consumer electronics and wireless broadband applications.
The chipsets also support wireless multimedia and draft 802.11e Quality of Service (QoS) specifications, providing advanced features for delivering wired-quality video and audio content via a wireless connection.
